Discretize the water level peak shift of the regulator SWOs along the Delaware River and the Schuylkill River.
The SWOs water level time-series between July 22, 2016 and July 28, 2016 were extracted from the Telog server. There is 1.60 in of rainfall on July 25, 2016.
SWOs on the Delaware River showed a delayed peak at upstream regulator than the downstream regulators, which can be as much as 30 minutes. Bottomline: use multiple tidal zones to represent the pattern variants. SWOs on the Schuylkill River are all synchronized quite well.
Bottomline: use a single tidal zone for all Schuylkill regulators.
